XBeeP-24B-if an API firmware is loaded, turn on "Enable API" on the "PC Settings" tab

XBeeP-24ZB-EVEN with an AT firmware loaded, "Enable API" on the "PC Settings" tab must be ON-"Test/Query" only works if you turn on "Enable API"-in order to READ, "Enable API" must be OFF-when the window full of text tellin you to press the reset button shows up, pull out the XBee from the FTDI board, and reconnect. (there is no reset button!)
